My OS is win 10 pro 64 bit and i usually post announcements in Google Groups, and I usually create the document in Google Docs, then copy and paste as a new topic in google groups. &nbsp;<br />
While in Google docs and while working on a document, there seems to be a grey sleeve like, as u can see in the attached file, which keeps scrolling down and covering the text whenever I scroll down using my mouse using the centre wheel. &nbsp;I have still not been able to figure out why this is happening, and it does not seem to go away. <br />
Hope the experts can please suggest how to fix this issue. &nbsp;Thank u.<br />
